What is the correct way to deal with a 75-year-old female relative who does not pray due to Parkinson's disease and her inability, knowing that she did not pray previously, and do the relatives bear a sin if they do not repeatedly try to urge her to pray, and should she be boycotted?

This woman must be reminded that prayer is not waived as long as one is conscious. She must pray according to her ability, as evidenced by the hadith of Imran ibn Husain: "Pray standing; if you are unable, then sitting; if you are unable, then on your side." It should also be clarified that prayer is the pillar of the religion and its second fundamental principle, and that abandoning it poses a grave danger. Continue advising her gently and wisely, and treat her kindly with service and good words. Abandoning her is not permissible unless such abandonment serves as a deterrent and leads to her repentance, and only to the extent necessary.
